  3. 3. www.epa.gov We are facing two conflicting realities Overview The right standard The right cost The right time Summary <ul><li>Arsenic is around us. </li></ul><ul><li>It is a common element that occurs naturally in: </li></ul><ul><li>water </li></ul><ul><li>soil </li></ul><ul><li>air </li></ul><ul><li>rocks </li></ul><ul><li>organisms </li></ul><ul><li>Studies have shown that long-term exposure to arsenic in drinking water can result in a range of health problems, including: </li></ul><ul><li>increased cancer risks (particularly skin, bladder, and lung cancer) </li></ul><ul><li>adverse cardiovascular, pulmonary, immunological, neurological, and endocrine effects </li></ul>
  4. 4. www.epa.gov The choice is clear The standard for levels of arsenic in drinking water must be lowered. It must be lowered as soon as possible. Overview The right standard The right cost The right time Summary
  5. 5. www.epa.gov A responsible and effective strategy requires additional elements beyond the right standard Overview The right standard The right cost The right time Summary The right standard The right cost The right time
  6. 6. www.epa.gov The right standard <ul><li>The EPA will implement a 10 ppb standard for arsenic in drinking water. </li></ul><ul><li>The current standard is outdated. </li></ul><ul><ul><li>The current standard—50 ppb—has been the nationally accepted health standard since 1942. </li></ul></ul><ul><li>The current standard is unsafe. </li></ul><ul><ul><li>In 1999, the National Research Council (NRC) issued a report declaring that the 50 ppb standard was an unsafe public health risk and “requires downward revision as promptly as possible.” </li></ul></ul><ul><li>In both instances, the Clinton Administration waited until January 2001 to recommend a reduced standard for arsenic. </li></ul>Overview The right standard The right cost The right time Summary
  7. 7. www.epa.gov The right cost <ul><li>The EPA will review the costs of implementation to ensure that the new standard can be achieved without putting an unfair burden on taxpayers. </li></ul><ul><li>Annual costs of complying with the new standard can be costly </li></ul><ul><li>The EPA will review options to lower costs </li></ul><ul><ul><li>This includes exploring new technology and innovative solutions such as creating consortia of small municipalities to share costs </li></ul></ul>Overview The right standard The right cost The right time Summary estimated cost of complying (per person per year)
  8. 8. www.epa.gov The right time <ul><li>The EPA will achieve the new standard nationally by the 2006 deadline and ahead of that deadline in many areas. </li></ul><ul><li>The EPA will put together a timeline that achieves full compliance by 2006 </li></ul>Overview The right standard The right cost The right time Summary 2001 2002 2003 2004 2005 2006 national compliance by percentage * for illustrative purposes only
  9. 9. www.epa.gov Summary <ul><li>The standard for levels of arsenic in drinking water that has been in place since 1942 is both outdated and unsafe. </li></ul><ul><li>The EPA will employ a three-part strategy to achieve a new safer standard: </li></ul><ul><ul><li>The EPA will implement the new 10 ppb standard </li></ul></ul><ul><ul><li>The EPA will explore options to reduce costs of complying with the new standard </li></ul></ul><ul><ul><li>The EPA will implement the new standard nationally by the 2006 deadline </li></ul></ul>Overview The right standard The right cost The right time Summary
